Spline curves ( circular biarcs)

Hi I am working on a project which requires some random data to be curve fitted using circular arcs or straight lines within a given tolerence range. Now the objective is to find the centre of the circle of each segment and the arc angles. I have tried using rscvn but am unable to understand the knots concept and am in need of urgent assistance.

As long as 3 points are not on a line, then these points will fall on a circle. A method I used (a long time ago) was to create a line between the first and second point, and a line between the second and thrid point. Next, draw a perpendicular line through the middle of the first line. Then, draw a perpendicular line through the middle of the second line. Where these lines intersect is the center of your circle.

I would ofter the code I used, but it isn't in Matlab and I am not even sure where it is.
